Alternative particle identification techniques to Cherenkov detectors

Alternative particle identification methods to Cherenkov techniques are reviewed. Particular focus is given to recent advances in Transition Radiation Detectors (TRDs), improvements in dE/dx ionization loss by cluster counting, and Time of Flight (ToF) techniques. In each case several state of the art detectors are highlighted. For advances in ToF techniques, the status of fast photon detectors and electronics developments is summarized.
